Hit, go advanced below.
It will bring up another page
Look for manage attachments
A new window will pop up and you can choose your pictures. I pull them from my desktop. Upload them and then hit submit.

My computer has been acting up and sometimes wont let me add attachments. I have no idea why. Its says waiting to down load then I get a message server was not found? Other days it will work. It is frustrating . I will go look at your pictures . Are they growing up to be sweet nice girls? How old are they now?
